State estimation is a critical process in control systems and signal processing that involves inferring the internal state of a system from measurements, often in the presence of noise and uncertainty. It is essential for applications like navigation, robotics, and power systems where accurate knowledge of the system's state is crucial for decision-making and control.

Noise refers to any unwanted or disruptive sound that interferes with normal auditory processing, communication, or comfort. It can originate from various sources such as industrial activities, transportation systems, and urban environments, impacting both mental and physical health.

noise

Uncertainty refers to the lack of certainty or predictability in outcomes, often arising from incomplete information, complex systems, or inherent randomness. It plays a critical role in decision-making, risk assessment, and scientific modeling, necessitating strategies to manage and mitigate its effects.

Applications of state estimation

Navigation is the process of accurately determining one's position and planning a route to a desired location, utilizing various tools and techniques to ensure safe and efficient travel. It encompasses a wide range of methods from traditional celestial navigation to modern GPS technology, adapting to different environments such as land, sea, air, and space.

navigation

Robotics is an interdisciplinary field that integrates computer science and engineering to design, construct, and operate robots, which are machines capable of performing tasks autonomously or semi-autonomously. The field aims to enhance efficiency and precision in various applications, from manufacturing and healthcare to exploration and personal assistance.

robotics

Power systems are complex networks that generate, transmit, and distribute electrical energy to consumers, ensuring reliability and efficiency while balancing supply and demand. They encompass a wide range of components including generation plants, transmission lines, substations, and distribution networks, all integrated with advanced control systems for optimal operation.
